The ZC-203AW fully automatic transformer ratio group tester is mainly used to supervise the quality of transformer products during production and use, to prevent inter turn short circuits, open circuits, connection errors, internal faults or contact faults of voltage regulating switches. The instrument is easy to operate, has complete functions, stable and reliable data, fast testing speed, and can meet the needs of various large, medium, and small transformer ratio tests. It is an ideal testing instrument for the power industry department.
Test purpose:
① Check if the transformation ratio matches the nameplate value to ensure that the required voltage transformation is achieved
② Check if the indicated position of the voltage tap changer is correct
③ Checking the turns ratio of each coil can determine whether there is a turn to turn short circuit in the transformer
④ Measure the imbalance of the transformation ratio of the three-phase transformer itself
⑤ Provide the accuracy of the transformer ratio to determine whether the transformer can operate in parallel
Product advantages:
① Widely used: transmission and distribution transformers, phase-shifting transformers, traction transformers, balance transformers, etc
② Easy to operate: One connection can measure data such as transformer ratio, group, phase shift angle, and tapping
③ Wide measurement range: 1~9999.9
④ Measurable phase shift angle: can measure the phase shift angle of a rectifier transformer and a phase-shifting transformer
⑤ Fast testing speed: three-phase synchronous output, fast testing speed, less than 5 seconds
⑥ High measurement accuracy: The equipment adopts a 16 bit high-precision AD and high-speed DSP processor, effectively ensuring measurement accuracy and anti-interference ability
⑦ Automatic data synchronization: Built in WIFI Bluetooth module for active data upload
Notes:
① When measuring, do not touch the sample.
② If the test line is short circuited and the high and low voltage are reversed, the fuse will be blown. After the fuse is blown, if a measurement is performed and the message "Measuring, please wait!" is displayed, then stop and shut down. Replace the fuse with the same capacity and retest.
③ The connection should be maintained in good contact, and the instrument should be well grounded!
④ The workplace of the instrument should be away from strong electric fields, strong magnetic fields, and high-frequency equipment. The smaller the interference of the power supply, the better. It is advisable to choose lighting lines. If the interference is still significant, the instrument can be powered by an AC purification power supply. The capacity of the AC purification power supply should be greater than 200VA.
⑤ When the instrument is working, if there is a display disorder on the LCD screen, no response when pressing all buttons, or if the measured value differs significantly from the actual value, please press the reset button, or turn off the power and operate again.
⑥ If there are no characters displayed on the monitor or the color is very light, please adjust the brightness potentiometer to the appropriate position.
⑦ The instrument should be stored in a dry and ventilated place.
